Huber KISS Circulator



The KISS K6 Circulator (cooling bath thermostat) has an insulated cooling bath and is well-suited for the thermoregulation of objects placed within the bath.

Designed for applications such as temperature control sampling, material testing analyses, and more, KISS Circulators are versatile machines.


The environmentally friendly choice.

Huber’s chilling fluid for this circulator is made of natural refrigerants, which means that this product is an environmentally friendly solution when compared to more wasteful competitors.

Automatic refrigeration adjustment.

The baths of each unit feature automatic refrigeration adjustment, which reduces energy consumption while keeping waste heat down.

Safety built right in.

Low-level protection prevents overheating and fulfills the requirements set forth by safety class III/FL.

The KISS Circulators can also be used for externally-attached applications (via the pump connections) located in the rear of the circulator. The KISS controller is easily operated and is perfect for continuous and semi-continuous processes.
